A synonym for "with" used by the nearly-illiterate l33tspeakers. I wouldn't mind if they did it once or even twice a comment/post, however it seems there's a coalition that decides what misspelled words to use (???). The main definition of "wit", which you probably know already, means the ability to make jokes and exercise intellect quickly without much thought. Someone who is able to make apropos puns would display wit. Fitting, since people who are poor spellers don't generally have much wit.

a tool of the human mind; sometimes used to get oneself "layed"; a compilation of knowledge typically set forth through common vernacular or nomenclature,(use words with as many syllables as possible..it make you soun smart).Many times the sole asset of the participant's arsonal of personal selfworth, ie; the only multitasking I am proficient at is,talking and pissing people off at the same time.
